Distributed Caching Mode Options

Sites that require timely or reliable access to the latest data should use one of the distributed caching modes that Oracle ATG Web Commerce provides. The choice of a distributed caching mode depends on a number of requirements.

Distributed TCP

The following requirements apply:

Real-time access to item changes

Infrequent updates to cached items

Modest number of item caches to monitor

Distributed JMS

The following requirements apply:

Reliable delivery of invalidation messages

Infrequent updates to cached items

Large number of item caches to monitor

Distributed hybrid

The following requirements apply:

Real-time access to item changes

Large number of cached items to monitor across many clients

Infrequent updates to cached items

A site that uses distributed hybrid caching must provide enough server memory to support a large GSACacheServerManager. For more information, see Optimizing Performance later in this chapter.
